Page History
RDK is a community-based project that
...
enables developers, vendors, and cable operators to
...
utilize a defined stack of software on one layer
...
for provisioning set-top boxes and gateways. Unique features of RDK, such as its commitment to open source,
...
the speed, and flexibility of RDK-based devices
...
, set it
...
apart from
...
conventional
...
set-top software stacks.
The standardized RDK‐V
...
stack provides a common method
...
for managing complex video and management functions
...
, including rendering, content, content security, device management, networking,
...
and peripherals.
...
The RDK‐V Feature List is categorized
...
based on the
...
following functions
...
. Enhancements and new features are developed and contributed asynchronously by members of the RDK Community.
